Not enought memory is available to issue the needed Domain Name Resolver(DNR) query or to build the DNR cache
The domain name server has returned an error
None of the known name servers are responding
This domain name does not exist
No name server can be found for the specified name string
No result procedure is passed to the address translation call when the resolver must be used to find the address
The name specified cannot be found in the cache. The domain name resolver will now query the domain name server and return the answer in the call-back procedure
The hostname field had a syntax error. The address was given in dot notation (that is, W.X.Y.Z) and did not conform to the syntax for an IP address
No gateway available to manage routing of packets to off-network destinations
Insufficient internal driver buffers available to fragment this packet to send
the icmp echo packet was not reponded to in the indicated timeout period
The destination host is not responding to address resolution reQuests
The packet is too large to send without fragmenting and the Don’t Fragment flag is set
A stream is already open using this local UDP port or a TCP connection already exists between this local IP address and TCP port, and the specified remote IP address and TCP port
The last network action timed out
The connection with the server came halfway up and then failed
The Read Data Structure refers to receive buffers not owned by the user
The receive buffer area pointer is 0
The TCP connection was broken; the reason will be given in a Terminate Asynchronous notification routine
An open stream is already using this receive buffer area
The specified TCP or UDP stream is not open
64 TCP or UDP streams are already open
This TCP stream has no open connection
The TCP or UDP stream already has an open connection
The total amount of data described by the Write Data Structure was either 0 or greater than 65535 bytes - array bounds exceeded or invalid
A TCPClose command was already issued so there is no more data to send on this connection
Error in getting an address from a server or the address is already in use by another machine
Not enough room in the application heap (Mac 512K enhanced only)
